The emerging nanotechnology paradigm, Quantum Dot Cellular Automata (QCA) in particular, is gaining a wide
recognition due to its high speed, nano feature size and considerably low power consumption. The QCA architecture not
only provide potential alternative for Complementary Metal Oxide Semiconductor (CMOS) circuits but its multilayer
topology facilitates an added benefit of cost efficacy and immunity towards random interference. Moreover, design of
programmable logic devices in QCA is vital to promote the multi-utility and resiliency of the computing circuits. This paper
presents the multilayer designs of 2×4 and 3×8 decoder circuits in QCA framework with 55.1% and 51.17% better cost
efficiency respectively, over the earlier reported designs. The presented 3×8 decoder circuit is further utilized to implement
Programmable Logic Array (PLA) to realize Boolean functions of adder and subtractor. The presented circuits are cost
effective and showcase the significance of programmable devices in nano-computing.
